| 摘要 |
A high-precision microminiaturized particle sensor composed of a darkroom (1), a converging lens (2), a collecting lens (3), an infrared LED (4), an optical receiver (5), a diaphragm (6) and a circuit. The microminiaturized particle sensor can detect the density of particles in air with high precision, and the sensor, compared with traditional sensors, has the features of high precision, low costs, small volume, low power consumption, stability and reliability, acid and alkali corrosion resistance, anti-static performance and convenient use, and can be widely used for particle detection in various environments. |
